CUT-OUT ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed April 25, 1908. Serial No. 428,195.

To all whom it may concern:

Be it known that we, BENJAMIN F. SHEIB- LEY and lVIL mLM MoLLER, citizen of the United States and subject of the King of Denmark, respectively, residing at Lewistown, in the county of Mifilin and State of Pennsylvania, have invented certain new and useful Improvements in Cut-Out Attachments for Internal-Combustion Engines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Our invention relates to internal combustion engines and has for its object to provide a cut out device or attachment therefor for the purpose of simultaneously cutting out the combustible gas from the cylinders and breaking the electric circuit, thus cutting out the ignition.

In the operation of motor vehicles it fre quently becomes necessary to suddenly cut out the engine, as for instance when coming upon a rut or obstacle in the road or whenever occasion requires it. In cutting out the engine under the usual conditions the same is accomplished generally by cutting out the spark and by throttling the carbureter; The engine, however, continues to turn over and if the carburetor is throttled a certain amount of combustible mixture is carried into the cylinders and consequently wasted;

.or if the carburetor is throttled to too great ing our attachment can be instantly cut out without interfering in any way with the commutator or timer and without throttling the mixture, thus instantly cutting out the ignition and causing the engine to'cease to take into its cylinders any combustible mixture, thus saving the electric current and Our invention therefofe has for its object to provide a cut out device or attachment for internal combustion engines; which by the operation of a single lever or other suitable means for conveying motion, the ignition is cut out and the combustible mixture is prevented from entering the engine cylinders simultaneously. The advanta es' of this attachment aside from the fact t at it furnishes instant control over the engine and economizing in electric current and fuel is that it allows the cylinders to take in a quantity of cool atmospheric air, thereby reatly facilitating the cooling of the cylinders, and allows the pistons to perform a number of strokes-thus enabling the same to carry a quantity of lubricating oilover the walls of the cylinder, for the reason that as soon as the i ition of the combustible mixture ceases, te extreme heat caused thereby and which burns the oil from the walls of the cylinders ceases, allowing the walls of the cylinders to again become coated with oil which is carried up by the pistons.

A further object of our invention is to provide. a cut out device or attachment for internal combustion engines which can be quickly and easily applied to all existing types of engines whether of the two or four stroke type, and without altering the engine or interfering with its regular operation in .the slightest degree.

A further object of our invention is to rovide a cut out device or attachment for internal combustion engines which is extremely simple in its construction and which can be ap lied to an engine in a short period of time y any ordinary mechanic. No special tools or implements or particular knowledge of the engine is required in order to efi'ectually equip an engine with the device.

With these objects inview our invention conslsts 1n the novel'construction and a1" rangement of parts of the attachment; and our invention consists in the arrangement of the valve and the circuit breaker operated thereby.

Our invention also consists in providing a valve and circuit breaker 'between thecarbureter or mixing device and the intake valves or intake port of an internal combustion engine.

Our invention also consists in certain other novel details of construction and in certain combinations of parts all of which will be fully described and afterward specifically pointed out-in the appended claims.

Referring to the accompanying drawings:

Figure 1 is an elevation of an internal combustion engine of usual type showing our cutout attachment applied thereto. Fig. 2 is ,a front' elevation of an internal combustion engine of usual type showing our cut out attachment applied'thereto. Fig. 3 is a longitudinalsectional view through the cut I out attachment.

same

ing with the intake manifold of the engine,

and 5 indicates a carbureter or mixing device of any .design or construction. It will be seen from Figs. 1 and 2 that the: attachment 2 is applied to the intake pipe 4 at a point between the c'arbureter or mixing device 5 and the intake manifold of the engine, and the attachment is preferably applied as near as possible to the intake manifdld and intake valves.

Referringnow to Fig. 3 it will be seenthat the attachment 2 comprises a short cylinder 6 having one end threaded and a hex nut 8 formed thereon, said hex nut 8 providing a shoulder 9 as shown. Arranged within the cylinder 6' near the outer end and 17 which are preferably secured to the thereof is a guide 10 through which the valve stem 11 of the valve 12 passes. A coil spring 13 bearing against the guide 10 and carried on the valve stem 11 is provided for normally seating the valve 12 in a seat 14 formed on the outer end of the. cylinder 6. Secured over theouter end of the cylinder as shown in Fig. 4 is a bracket 15, said bracket being provided with two arms \16 cylinder 6. by means of screws 18. 'The bracket 15 is provided with an opening 19 through which the valve stem 11 passes, and carried on said bracket '15 is the circuit breaker 20.. Said circuit breaker 20., as shown, in Fig. 3, comprises a plunger 21 and plunger stem 22, said plunger and stem being accommodated in a small shell or cylinder 23, and the outer end of said cylinder 23 is provided with a plug 24 of insulating material, said plug 24 having a flange 25 thereon extending over the end ofthe shell or cylinder 23 covering the same, as clearly shown in Fig. 3. Threaded on the plug 24 or other- .wise suitably secured thereon is a small.

metallic band 26 by means of which the wire 27 is secured to the circuit breaker. The plug 24. is provided with ,a central opening through which the plunger stem 22 passes,

and the outer end of said stem is provided 3 A binding post 30 is provided on the bracket 15-to which the wire 27 is secured and to which the ound wire 31 of the cir cuit is also secured.

Having thus described the several parts of our invention its operation is as follows: The attachment being provided on an internal combustion engine at any convenient place between the carbureter or mixing device 5 and the intake valves or intake ports, of the engine; as shown in Fig. 3 an operating cord 32 is secured to the outer end of the valve stem 11, said cord leading tofa suitable lever or other device within easy reach of the operator of the machine'in such manner that the valve 12 canbe quickly un seated by the operating cord 32. When the operating cord 32 is pullel the valve 12 is opened against the pressure of the coil spring 13 on the valve stem ll'which movement ofjthevalve 12 moves the plunger 21 .of the circuit breaker carrying the bar 28 on the end of the plungerstem 22 out of contact with the metallic band 26 on the outer end of the circuit breaker. As the ground wire passes to the binding post 30 and said post s connected with the metallic band 26 on the circuit breaker by means of the wire 27 the current is grounded through the metallic band 26,cross-bar 28, plunger stem 22, plunger 21, cylinder 23, bracket 15 andlcylinde'r. Got the attachment. 1 As soon,.therefore, as the valve 12 is raised in the position shown in Fig. 4. the bar 28 on the plunger stem 22 is carried out of contact with the metallic band 26, thus breakingthe circuit as the binding post 30 is insulated from the bracket 15' as clearly shown in Fig. 3. The

result is that communication between the engine cylinder andfthe atmosphere is effected at a point between the c'arbureter or mixing device 5 and the intake" valves or ,intake ports of the engine. As the pistons therefore perform their suction stroke atm'ospheric air is drawn into the cylinders throughthe attachment instead of througlfi the carbureter or mixing device 5. This charge'of atmosphericair into the cylinders is notcombustible and therefore there isnothing within the engine cylinders t0 ignite, but in orderto absolutely insure an instant cut out of theengme the circuit breaker is simultaneously operated by the valve 12, thus breakin the circuit and cutting outjthe ignition. continues to turn over for a number of revolutions during which time no combust ble e engine of course seated as shown in Fig.13 which instantlymixture is being drawninto the cylinders,

and the circuit being broken the electric current is being saved which allows thebatteries or source of'energy to recuperate as is of course clearly evident. When it is desired to allow the engine-to again take up its revolutions regularly the valve 12. 15

cuts out the atmospheric air from the cyl-' inders causing the cylinders .to take ;-their charges of combustible mixture through the carburetor or mixing device 5 simultaneously closing the electric circuit thus cutting in the-ignitlon.

A further advantage of the application'of our device to an internal combustion engine is that in the event of deran ment of the intake valves or by reason 0 an improper seating any back firing of the combustible gases which might occur, passes out into the atmosphere through the valve 12, thus re-' lieving the carbureter or mixing device of this pressure which is frequently so great as to disrupt and demolish the carbureter or mixing device. The normal action of the engine pistons drawingthe combustiblenninture into the engine cylinders tends to seat the valve 12 and maintain san'le in a seated position, the coil spring 13 on the valve stem 11 only being of such tension as to'insure the proper seating of the valve while the engine 1s at rest or in starting ...A slight pressure therefore Within the intake mani fold or within the intake pipe 4 between the intake valves or ports and the carbureter or mixing device 5 will instantly unseat the valve 12 and relieve the pressure, thus insuring the carbureter or mlxln device against any back pressure caused by back-firing.

As will' 'ap car from" the foregoing-description the Y ocation of the attachment onan internal combustion engine is entirely immaterial so long as the same is applied at a point between the carbureter or mixing device 5 and the. intake valves or ports,

' although it is referable to locate the same at a point as c ose as possible to the intake valves or ports as clearly shown in Figs. 1

and 2.
